Play Mode: Multi-Part Bonding
1. Instructions
Multi-part bonding involves assembling multiple injection-molded soft-gel parts to create larger, segmented, and more complex structures. This method supports two main approaches:
Method 1: Self-Bonding with Soft-Gel
Use uncured soft-gel material as a “structural adhesive” by applying it to the bonding area. Thanks to its natural fluidity and tackiness, the material forms a seamless connection after cooling and curing.
- Recommended material hardness: 0A–40A, with strong adhesion and good flowability
- Tips: Ensure bonding surfaces are clean and oil-free; let sit for 3–5 minutes after injection to cure
- Applications: Modular connections, tubing joints, structural linking, creative assemblies
Method 2: Adhesive Bonding
Use PVC-compatible adhesives (such as solvent-based PVC glue or toy-safe adhesive) to bond multiple cooled soft-gel parts afterward.
- Suitable for higher-hardness parts or reinforcement repairs
- After applying glue, leave for 30–60 minutes to fully cure
- Useful for bonding dissimilar materials, offset structures, or encapsulating complex assemblies
Key Advantages
- Glue-free bonding: Soft-gel’s thermal adhesion allows strong connections without additional glue
- Versatile combinations: Supports offset assembly, modular builds, and multi-segment continuous structures
- Flexible operation: Enables on-site instant bonding or post-process adhesive assembly
- Greater creative space: Breaks mold size limits to build larger or multi-functional components
Material Recommendations
- Best to use 0A–40A soft-gel as bonding medium for superior flowability and adhesion
- Keep bonding areas clean, dry, and free from dust or grease
- When using adhesives, pair with ABS, PP, PVC, or other hard parts with natural bonding properties for stronger connections
🎨 Application Examples
- 🤖 Pneumatic Bionic Muscle Structures: Connect multiple soft-gel tubes into a complete “pneumatic muscle” system
- 🧩 Modular Assemblies: Combine multiple small molded parts into large structural models
- 🎯 Soft-Gel Toys/Building Blocks: Such as detachable squish toys, bumpers, or interlocking pieces
- 🛠 Repair or Reinforcement: Ideal for multi-material assemblies or strengthening replacement parts
Gum Mold Play Mode
- Pre-print the gum mold and accessories (use PETG or other heat-resistant materials for the gum mold; no specific material required for teeth)
- Prepare 0A raw material, PVC pigments, and PVC adhesive
- Use Saltgator to inject the gum mold; after cooling, obtain the soft-gel gum model
- Trim off excess edges from the gum model with tools
- Place the pre-printed teeth into the gum slots and apply PVC adhesive to fix them
- Wait for the PVC adhesive to cure, resulting in a complete gum-and-tooth model
Pneumatic Gripper Play Mode
- Pre-print the mold and its accessories (recommended: PETG or other heat-resistant materials). Note: the gripper requires two mold pieces.
- Prepare 20A raw material (20A or 40A is recommended for best results), PVC pigment, and PVC adhesive.
- Use Saltgator to inject the pneumatic gripper mold. After cooling, you will obtain a soft pneumatic gripper model.
- Trim off excess edges from the gripper model using tools.
- Use PVC adhesive to bond the two mold pieces together to form a single pneumatic gripper.
- Repeat the above steps to make three pneumatic grippers. Then use PVC adhesive to attach the grippers to the corresponding positions on the accessories.
- Wait for the PVC adhesive to cure, and you will have a complete pneumatic gripper model.
